Thanks, I'll check out the manuals. I hope it's something simple.Welcome from Alberta Canada
As @Nad_Yvalhosert pointed out, it's most likely a 4.3, if not, we definitely need some pictures.
If you haven't done so already, go to the engine and performance section, there is a "sticky" thread there with all the factory service repair manuals there available for download. They should have a section in them that should help fix your speedo issue.
If the hood you are looking at is a cowl induction one, that's a cool score. Should fit no problem.
